3PC Stainless Steel Ball Valve 2000WOG Extended Stem

3PC Stainless Steel Ball Valve 2000WOG Extended Stem is designed for insulated pipelines, buried installations and other applications where the valve operating point needs to be extended. The valve features a 316 stainless steel body, ball and stem, a three-piece construction, and NPT or BSP threaded connections. The extended stem allows the valve to be operated away from the insulated or buried section of the pipeline.

Key Features

1. Extended Stem for Insulated and Buried Pipelines

The extended stem places the operating point above or away from the pipeline connection area. This configuration is useful where pipe insulation, underground installation or limited access makes a standard stem difficult to operate. The stem also uses an anti-blowout structure for pressure service.

2. 316 Stainless Steel Construction

The body is made from ASTM A351 CF8M stainless steel, while the ball and stem use ASTM A182 F316. These materials provide corrosion resistance for compatible water, oil, gas and industrial fluid applications. The RPTFE seat is specified for the listed temperature range and service conditions.

3. Three-Piece Body

The three-piece body allows access to the internal components for inspection and maintenance. The valve can be disassembled when the seat, seals or other internal parts need to be checked or replaced, which is useful for maintenance of installed pipeline systems.

4. 2000WOG Pressure Rating

The 3PC Stainless Steel Ball Valve 2000WOG Extended Stem is specified for high-pressure on-off fluid control, with a maximum pressure of 1975 PSI listed in the product data. The applicable working pressure should be confirmed according to valve size, temperature, medium and the relevant pressure-temperature rating.

Standards and Quality Control

The valve is manufactured according to ISO 17292/API 608 requirements, with pressure-temperature ratings referenced to ASME B16.34 and testing and inspection according to API 598. Production inspection includes incoming material checks, pressure testing, sealing tests and finished valve inspection.

ISO 9001 and CE documentation is available for applicable valve configurations. Material test reports can also be provided according to order and documentation requirements.

Applications

The 3PC Stainless Steel Ball Valve 2000WOG Extended Stem can be used in pipeline systems where extended valve operation is required, including insulated process lines, buried pipelines, water treatment, oil and gas systems, chemical processing and general industrial fluid control.

Before selection, check the pipeline medium, operating pressure, temperature, connection standard and available installation space. Material compatibility should also be confirmed for the body, ball, stem and seat.

FAQ

1. What is the extended stem used for?

The extended stem is used for insulated pipelines, buried installations and other locations where the valve operating point needs to be positioned away from the pipeline connection. It provides access to the valve without removing the surrounding insulation or exposing the buried pipeline section.

2. What materials are used for the valve?

The body is ASTM A351 CF8M (316), while the ball and stem are ASTM A182 F316. The standard seat is RPTFE (PTFE+15%fv). Other materials are available according to the required service conditions.

3. What pressure and temperature range does the valve support?

The product data lists a maximum pressure of 1975 PSI and a temperature range of -25℃ to 150℃. Actual allowable pressure depends on valve size, temperature, medium and the applicable pressure-temperature rating.

4. What thread connections are available?

The standard thread connections are NPT and BSP. Other connection requirements can be discussed according to the pipeline specification.

5. Can material and sealing components be customized?

Yes. Other body, ball, stem, seat and sealing materials can be supplied according to the operating medium, pressure and temperature requirements.

6. What documents are available?

Applicable product documentation can include material test reports, inspection records and ISO 9001 or CE documentation for the relevant valve configuration.

7. How is the valve packaged for export?

The valves are packed in corrugated cartons and plywood cases for export shipment. Packaging can be adjusted according to valve size, order quantity and transportation requirements.
